The invention relates to medical equipment, in particular to simple automatic peritoneal dialysis equipment. The equipment comprises a raw water filter, an EDI electric deionizater and a raw water processing device composed of I and II class reverse osmosis units, a peritoneal dialysis liquid confecting device composed of a dual-cavity proportioning pump, a peritoneal dialysis liquid confecting three-way solenoid valve and a peritoneal dialysis liquid container, a peritoneal dialysis treating device composed of a peritoneal dialysis treating three-way solenoid valve, an abdominal cavity innerguide coupling, a waste liquid container and a negative pressure pump as well as an automatic control system composed of an ARM singlechip which carries out finishing and programming on the collectedsignal; wherein the signal input interface of the ARM singlechip is respectively connected with the raw water processing program module, a treating program module, a correction treating program module and a safe monitoring program module, and the signal output interface thereof is connected with a power driver which controls the external parts under the instruction of the ARM singlechip. The invention integrates water treatment, peritoneal dialysis liquid confecting and automatic peritoneal dialysis treatment, totally closed type one machine treatment is realized, and treating expense can be greatly reduced.

A semi-automatic medicine mixing machine for infusion medicine mixing comprises a stand, an infusion tube (3) fastened to the stand, and an infusion needle (2) and a medicine bottle separately connected to two ends of the infusion tube (3). The stand is provided with a power mechanism and a pressing member connected to the power mechanism. The pressing member is driven by the power mechanism to intermittently press the infusion tube (3), and the infusion needle (2) is inserted into the medicine bottle. The power mechanism drives the pressing member to intermittently press the infusion tube (3), so that the semi-automatic medicine mixing machine for infusion medicine mixing enables a liquid medicine to flow, so as to mix the liquid medicine without involving human participation, thereby improving efficiency and ensuring safety of medicine mixing.

3-n-Butyl-1-isoindolinone and use thereof for preventing or treating cerebral infarction. The compound is prepared by: 1) employing phthalimide as a starting reactant, contacting a nucleophilic Grignard reagent with the original reactant to add an alkyl group to a carbonyl carbon of an amide bond of the original reactant, thus yielding an intermediate; and 2) removing an oxygen atom connected to a third carbon atom of the intermediate in the presence of boron trifluoride diethyl etherate as a catalyst and triethylsilane as a reductant.
